Vacuum Hose Adapter Assembly for Diameter Transition and Suction Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hose adapters for vacuum systems in animal grooming tools fail to provide an efficient and secure connection between hoses of different diameters, leading to suboptimal suction and hair collection efficiency.
Innovation Solution
A hose adapter assembly with a first connector portion of larger transverse dimension and a second connector portion of smaller dimension, featuring inwardly-projecting ribs for hose retention and a vent opening with a movable closure to adjust suction, facilitating effective connection and suction control between vacuum devices and grooming tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a hose adapter connects hoses of different diameters, then adaptability is improved, but maintaining intimate passageway connection becomes difficult
Solution Approach 1:
The adapter employs nested connector portions where a first connector portion with larger diameter and a second connector portion with smaller diameter are integrated into a single adapter body. The transition portion smoothly connects these nested connectors, allowing hoses of different diameters to be connected while maintaining intimate passageway connection throughout the adapter structure.
Solution Approach 2:
The adapter serves as an intermediary device between hoses of different diameters. The transition portion acts as a mediator that smoothly connects the larger diameter first connector portion to the smaller diameter second connector portion, ensuring continuous and intimate passageway connection while adapting between different hose sizes.
2Reliability
If inwardly-projecting ribs are added to retain the hose, then connection reliability is improved, but device complexity increases
Solution Approach 1:
Inwardly-projecting ribs are added only to the second connector portion where hose retention is needed, rather than throughout the entire adapter. This localized feature provides effective hose retention through friction and mechanical engagement while minimizing the increase in overall device complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The hose adapter assembly ensures a secure and efficient connection between hoses of varying diameters, enhancing suction control and hair collection efficiency by maintaining intimacy of passageway and providing adjustable suction, thus improving the overall performance of vacuum systems in animal grooming tools.
Implementation Method 1
a vacuum device operatively associated with one of the first connector portion and the second connector portion
Implementation Method 2
permits the vacuum device to draw air through the hose, through the hose adapter, and into the vacuum device
Implementation Method 3
The interior surface of the second connector portion has a plurality of spaced, inwardly-projecting ribs which serve to engage the hose portion which extends into the second connector portion and retain the same in place

AI summary
A hose adapter defines a passageway therethrough and has a first connector portion and a second connector portion with the first connector portion being substantially larger in transverse dimension than the second connector portion. A transition portion is disposed between the first and second connector portions. A vacuum device is operatively associated with one of the first and second connector portions, and a hose is secured to the other connecting portion. In one embodiment, the hose adapter has a vent with an associated closure, which is designed to vary the opening in the vent and thereby alter the amount of suction created by the vacuum device. A plurality of interiorly-mounted, inwardly-projecting ribs are provided in the second connector portion to facilitate retention of a hose therein. A vacuum system employing the adapter is disclosed.
